2016 XF series boiling drier, SS vibro fluid bed dryer, GMP laboratory drying ovens
Descriptions
Boiling drier is also called as fluidize-bed. It consists of air filter, heater, fluidized-bed main machine, feeder, cyclone separator, cloth bag duster, high-pressure centrifuge fan and operation table. Because the properties of raw material exist difference, when equip the dust removing equipment, it should consider the practical need. It can select cyclone separator and cloth bag duster at the same time or one of them. In general speaking, it needs to select cyclone separator only for raw material that is large in specific gravity and cloth bag duster for powder and small granule raw materials that is light in gravity. Meanwhile there is air feeding device and belt conveyor for selection.
Separated granule solid raw material is fed into fluidized-bed drier through feeder. Fresh air through filtering and heating is sent to the bottom of fluidized-bed by fanand contacts with solid raw material on distributing plate. In the way the fluidized state is formed and the heat exchange between air and solid is carried out. The dried raw material is discharged from outlet and wasted gas is exhausted from the top of fluidized-bed where catches solid powder through cyclone separator, cloth bag duster.
Principle
The clean and hot air enters into fluidization bed through distributor of valve plate. The humidity raw material fed from the feeder from the boiling state by hot air. Because of the wide contact between hot air and raw materials, the time of drying is shoted. The air enters from front of bed, boiling in bed several minutes, and float from other of bed. The machine works in negative pressure.
Features
Automatic production can be realized. It is continuous drying equipment. Its features are quick in drying speed, low in drying tempment, it can guarantee the quality of products and is in conformity with the requirements of GMR.
Application
Drying operation of medicines, chemical raw material, foodstuff, grain processing, feed and so on. For example, raw medicine, tablet, Chinese medicine, foodstuff of health protection, drinking, feed, resin, citric acid and other powders. The suitable diameter of raw material will be 0.1-6mm. the best diameter of raw material will be 0.5-3mm.
Notes to Installation
The equipment should be laid down level and fixed with anchor bolt. The seal of each part should be good.
